本文介绍了一种在忘记MySQL root登录密码的情况下，通过修改配置文件并利用skip-grant-tables选项来绕过权限验证，进而更新root用户密码的方法。

===========================================================
二，忘记本地root的登录密码
解决过程：
1、编辑/mysql/my.ini
在[mysqld] 配置部分添加一行
skip-grant-tables

2、保存后重启mysql
[root@localhost etc]# service mysqld restart
Shutting down MySQL. [ OK ]
Starting MySQL. [ OK ]

3、登录数据库重新设置root密码
[root@localhost ~]# mysql -u root -p mysql
Enter password:
直接回车进入

3 rows in set (0.00 sec)

执行下列语句

mysql>use mysql;
mysql> update user set password=password("mysql") where user='root';
Query OK, 4 rows affected (0.00 sec)
Rows matched: 4 Changed: 4 Warnings: 0

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

4、删除/etc/my.cnf文件中添加的“skip-grant-tables”行，重启mysql；
用新设的密码就能正常登录了；
